Agenda
• Welcome and Team Introductions • Presentation
• SSFL Overview – DOE, NASA, Boeing Activities• Site-wide Groundwater Activities • Off-site conditions update• CEQA Update• Schedule Update
• Community Questions and Answers • Wrap up
• Please turn off or mute all noise emitting devices.• Please treat each other with the same level of respect you expect
from others.• Please limit cross conversations with fellow participants as it can be
distracting to the presenters and meeting participants.• Please hold your questions or comments until the question and
comment period of the meeting.• Please state your question as clear and succinct as possible. If we
are unable to get to your question during the meeting, the team will be available to address your question at the conclusion of the meeting.
• In the event there is videotaping taking place, please inform the videographer if you do not want your image or voice to be taped.
Guidelines for the Q&A Session
DTSC’s Mission
To protect California’s people and environment from harmful effects of toxic
substances by restoring contaminated resources, enforcing hazardous waste laws, reducing hazardous waste generation, and encouraging the manufacture of chemically
safer products.

NASA Status
• Soils characterizationDTSC reviewed and provided comments on the Data Summary Report
• Groundwater Four major investigation areas
• Soil and groundwater treatability studies
• Demolition program
Liquid Oxygen (LOX) Buildings
NASA Impacted Soils
The Boeing Company -The Bowl
Boeing Status
• Soils characterization• Field work nearly complete• Two of Nine reports submitted• DTSC finalizing comments
• Groundwater • Major investigation
areas almost complete• Treatability studies
Boeing Soil CharacterizationTan – Preliminary Soil Cleanup AreasHatch – Preliminary Soil Gas Cleanup Areas
Site-wide Groundwater
• Facility Investigation• Continued characterization
21
• Quarterly groundwatermonitoring
• Groundwater Interim Measures• Operate wells from
source areas• Implement in 2016
Trichloroethene in Groundwater
Boeing (Areas I and III)• Submitted Site-wide Seep Characterization Report.• Fault Characterization work is ongoing.
• Four additional wells in Area 1• 2 of 9 RFI Data Summary Reports submitted
• Soil & Groundwater evaluations from overlying source areas.
• Treatability Study Field work for in-situ oxidation complete• Laboratory studies of bio-degradation ongoing – Reports
coming.
Site-wide Groundwater
• NASA (Area II)• Continued field work for four areas of impacted
groundwater (AIGs) near completion.• 14 boreholes drilled• Geophysics conducted at 41 new boreholes and existing wells• Packer Testing conducted at 41 locations• Vapor sampling conducted in selected boreholes• Passive soil vapor sampling at AIGs• Aquifer Testing at AIGs• Reporting in mid-2016
• Field work for the treatability study for bedrock vapor extraction completed.
Site-wide Groundwater
DOE (Portions of Area IV)• DTSC approved Final RFI Groundwater Work Plan• Implementating Work Plan. Field work includes:
• One Exploratory boring• 10 monitoring wells• Well rehabilitation (removal of FLUTe liners)• Gauging/sampling of monitoring wells and seeps/springs• Packer tests and borehole geophysics/video logging - select wells
Boeing (Area IV)
• DTSC review – Groundwater Data Gap Work Plan Addenda for Boeing Area IV.
Site-wide Groundwater
Off-site Issues
RunkleCanyon
SSFL & Off-site Drainages
• The Brandeis Bardin Institute Campus is safe for use by Faculty, Staff, Students, and Campers.
• Measures have been taken to prevent SSFL contamination from traveling onto Brandeis Bardin property.
• A physical Buffer Zone separates Brandeis Bardin and SSFL.
Any data demonstrating a threat to human health at Brandeis Bardin or any other areas from SSFL would result in DTSC taking immediate actions to stop that threat.
Brandeis Bardin Property – DTSC Conclusions

> Draft provisional look-up table
Runkle Property – DTSC Conclusions
DTSC reviewed data from both Runkle and SSFL.
• DTSC’s sampling efforts indicate no radiological contamination and did not confirm the earlier elevated levels. DTSC evaluated the entire 2005, 2007 and 2010 data sets.
• No pattern to indicate an on-site source or off-site release from Santa Susana Field Laboratory.
To access the Runkle Property information visit DTSC’s EnviroStor website: https://www.envirostor.dtsc.ca.gov/public/profile_report.asp?global_id=60000899
Site-wideCalifornia Environmental Quality Act
• Draft Program Environmental Impact Report (PEIR)Will assess potential environmental impacts:
• Implementing clean-up for all three responsible parties• Alternative routes/conveyance systems for material
transport• To the full range of resources areas including cultural and
biological
• Public review and comment period for the draft PEIR anticipated in September 2016
